In Cypress how to count a selection of items and get the length?

Question

I\'m starting to learn Cypress. I have a 4 row table (with a class of datatable). I can verify the number of rows this way:

cy.get(\'.datatable\').find(\'tr\         


        

Answer 1

From the cypress API docs .should() section, using an arrow function:

cy.get('.datatable').find('tr').should(($listOfElements) => {
   expect($listOfElements).to.have.length(4)
   // any other assertions, for example the below one
   // expect($listOfElements).to.have.any.keys('key1', 'key2')
})

This approach will allow you to use Chai BDD notation and assert more than one thing on your list of elements.
